There is provided a service node that is capable of serving a first user node in a first network including a control node. The first network is capable of communicating with a second network including a second user node. The service node comprises: a request receiving unit that receives a first user identity that identifies the first user node and a second user identity that identifies the second user node; a determining unit that determines whether a received message includes the first user identity as a destination, or the message includes auxiliary information that corresponds to the first user identity; and a modifying unit that modifies the destination of the message to the second user identity and modifies the source of the message to the first user identity in accordance with the determination result by the determining unit.
摘要:
A system for efficient routing in a multiple hop wireless communication network comprising a plurality of network nodes is presented. The system acquires quality information indicating link status between the infrastructure nodes. The link quality information is used in a route determination process in the infrastructure nodes using a predictive procedure. The link quality information includes information about a time varying information of the link status. The predictive procedure uses the time varying information of link status, and a router data packets according to the determined route.

The storage unit is configured to store image data of one or more devices that are connected to a local network. The obtaining unit is configured to obtain image data of device image obtained by capturing a device. The specification unit is configured to specify one or more local networks to be used for image matching. The image matching unit is configured to perform image matching of the obtained image data against the stored image data of one or more devices that are connected to the specified local network.
摘要:
In the first embodiment, the mobile phone 20 obtains the PCID from the CCE 10, and sends the PCID and the IMSI of the USIM of the mobile phone 20 to the CAPS 50. The MCC+MNC part of the IMSI is later used as the operator identification information by the mediation server 30, which is operated by the RO, in order to identify the SHO for the CCE 10. The MSIN part of the IMSI is later used as the user identification information by the account managing server 40, which is operated by the SHO, in order to identify the user of the mobile phone 20. The mediation server 30 forwards the account request from the CCE 10 to the account managing server 40 of the SHO identified by the operator identification information. The account managing server 40 generates the MCIM that is associated with the user identified by the user identification information.
